A calorimeter can be fancy and an expensive piece of hardware, or it can be simple.

可以是花哨的、昂贵的件，可以是简单的。

They put those in the bomb calorimeter and  they got a starting point for the calories.

们把这些物质放入弹式中，得到了的初始数据。

And this may look like a plastic bottle inside a koozie, but it's actually a calorimeter.

这可能看起来像 koozie 里面的塑料瓶，但它实际上是一个。

We also didn't include the heat capacity of our calorimeter itself.

我们没有包括本身的容。

The problem with bomb calorimeters is that  they burn foods to completion, but that's not what happens in the body.

炸弹器的问题在于它们将食物完全燃烧，但这并非人体内的实际情况。

It's just that luckily, in this specific case, they are related by our handy little calorimeter formula.

幸运的是，在这种特定情况下，它们通过我们方便的小公式相关联。

For a quick simple method, the calorimeter got us pretty close to the calculated value.

对于一种快速简单的方法，使我们非常接近算值。

The calorimeter walls and the thermometer were heated too, resulting in some of the produced heat not being accounted for.

壁和温度被加，导致一些产生的没有被考虑在内。

Most historians would consider the 1860s to be the birth of modern nutrition — this was around when German researchers pioneered the use of room-sized devices called calorimeters.

大多数历史学家认为 19 世纪 60 年代是现代营养学的诞生——大约在那时，德国研究人员率先使用了称为的房间大小的设备。

And you know the general setup by now: the chemicals in the calorimeter make up the thermodynamic system and everything else is the surroundings.

你现在已经知道了一般设置：中的化学物质构成了力学系统，其一切都是周围环境。

Now there's a simple formula that allows us to calculate the heat change of a reaction, simply by measuring the change in temperature that occurs in a calorimeter.

现在有一个简单的公式可以让我们算反应的变化，只需测中发生的温度变化即可。

A bomb calorimeter can tell us how much  energy is stored in that food sample, but this is the key thing, and I did not  realize this until I was researching it.

一个弹式器能告诉我们食物样本中储存了多少能，但关键在于， 这一点我直到研究时才意识到。
